JOHN VFRAZEE AND ANDREW .I. THOMAS, OF KANSAS CITY, MISSOURI COMBINEDCOOLER AND FILTER.

SPECIFICATION forming part of Letters Patent No. 334,426, dated January19, 1886.

(No model.)

To all whom it may concern..-

. Be it known that we, JOHN W. FRAZEE and ANDREW J. THOMAS, citizens ofthe United States, residing at Kansas City, in the county of Jackson andState of Missouri, have invented certain new and useful Improvements ina Combined Cooler and Filter, of which the following is a specification,reference being had to the accompanying drawing.

This invention has relation to a combined water cooler and lter; 'and itconsists, substantially, in the same as constructed, and in theparticular combinations of parts to be hereinafter distinctly described,and pointed out in the claims. v

The objects of our invention are to supply a cooler and lter that may beconstructed at small cost, one in which comparatively few parts areemployed, and one by which water or other liquid may be cleansed of itsimpurities in a thorough and rapid manner. These objects we attain bythe device shown in the accompanying drawing, wherein is represented invertical sectional elevation a combined cooler and lter embodying ourimprovements. i

The main design or result aimed at in the operation of our invention isto have the volume of water which the vessel contains destroyed of itsequilibrium, and then cause it, in again seeking to establish its levelor equilibrium, to pass vthrough the several ltering media arranged inthe tubes, as hereinafter described, whereby it is thoroughly cleansedof all impurities. A

In the accompanying drawing, A represents an upper tank or vesselfitting in the top of a lower vessel, B. The tank A is provided with anadditional or inner wall, a, the space between the two being filled withany suitable packing or non-conducting material, b, and the said tank isprovided with a lid or cover, c, fitting in the top thereof, as shown.In the bottom of the tank is formed an'opening, d, around which extendsa screw-threaded flange, e, to which is fitted a cap, f, having a seriesof perforations, g. Connecting with theopening d from beneath is theupper end of the iiltering-tube C, the same branching off to one side,

5o as shown, thence downward and upward, and

again downward and upward, the extremity thereof being fitted with aperforated cap, hv. The vertical portions of this continuons tube areconnected at top and bottom by horizontal sections i j 7c, and extendingdownward from the two last-named sections are threaded flangesl m n,each having a removable cap. These danges communicate with the interiorof the lteringtube, and the ltering material may be removed at any timeby simply unscrewing the caps; and so, also, in this way may the tube becleaned when desired. In the neck of the tube communicating with openingd we arrange a sponge, o, and we fill the hori- Zontal section of tube jwith charcoal and hair felt, the charcoal extending up a short distancein the vertical section l, and the hair felt extending up in like mannerinto the section 2. Then in the lower extremity of the section 3 wearrange a quantity of asbestus, and beneath that in the`horizontalsection k is arranged some large gravel, all as shown. In this mannerthe water will first enter the filtering-tube through the perforationsin cap g, thence pass through the sponge and iow down and pass throughthe charcoal and hair felt in the lower extremity of the sections l 2,rise up in the latter section, thence down into section 3, through thehair felt and gravel at the bottom thereof, and finally upwardin section4, and issue through the perforations in cap h, in a thoroughly filteredcondition, to be drawn off at any time through the cock p. By placing asuitable quantity of ice in the tank A the water will be cooled.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- 1. In a combined cooler and filter, the com-ICO ends by horizontal sections and provided at with the lower cappedflanges, Z m n, all set Io its extremity with :L perforated Cap, and theforth.
